District
West of IH 10 to IH 35
Utilized CORSIM to
analyze proposed conditions on 21 miles of controlled-access freeway/ tollway.
Mainlanes (both tax and toll lanes), ramps, interchange connectors and
collector-distributor roadways were analyzed to determine the optimal layout
for PS&E development by others.
IH 10, Bexar and Kendall Counties - TxDOT San Antonio
District
US 87 North of Boerne to IH 410
Utilized CORSIM
to analyze alternative ramp patterns and lane balance as part of the schematic
development of 19 miles of freeway from US 87 North to De Zavala Road. Project
also included analysis of the directional interchange with Loop 1604 and
analysis of the 6.5-mile section from De Zavala Road to IH 410 to suggest
bottleneck improvements required for the 2030 design year.
IH 35 Northeast Corridor Study, San Antonio - TxDOT San
Antonio District
IH 35 - North of Loop 1604 to US 281
IH 410 -
South of IH 35 to IH 35
IH 10 - West of Loop 13 to East of IH
410
Utilized CORSIM to analyze existing and proposed conditions of a
total of 21 miles of urban controlled-access freeway widening and
reconstruction. Multiple alternatives were studied including various
combinations of general-purpose lanes, express lanes, reversible lanes and HOV
lanes. Project included analysis of the directional interchanges of IH 35 and
IH 410 North (Fratt Interchange) and IH 410 South.
Loop 1 Field Change, Austin - TxDOT Austin
District
South of Parmer Lane to Wells Branch
Pkwy
Utilized CORSIM to analyze operations of ramp and access
improvements to the Loop 1 Tollway. The improvements initially modeled were as
shown on a design schematic provided by others. An alternative layout was
proposed and approved, resulting in over $2 million in savings.
SH 121 South, Tarrant and Johnson Counties - TxDOT Fort
Worth District
FM 1187 to US 67
Utilized CORSIM to analyze
operations for 13 miles of four-lane divided controlled-access tollway on
new-location, including operations of the opening day layout of two-lanes with
two-way traffic (one side of the ultimate section). Also performed iterative
runs to estimate year in which ultimate facility must be in place to avoid
breakdown in operation of the initial layout.
SH 45, Austin - Texas Turnpike Authority
East
of IH 35 to SH 130
Utilized CORSIM to analyze proposed conditions and
assist in the preparation of design schematics of 4 miles of urban six-lane
controlled-access tollway.
Loop 375, El Paso - TxDOT El Paso District
North of IH 10 to US 62 / US 180
Utilized CORSIM to analyze existing
frontage roads and proposed mainlanes for 8 miles of urban controlled-access
freeway. Various ramp patterns and intersection improvements were studied to
optimize the schematic layout.
IH 45 - TxDOT Houston District
Beltway 8 to FM
518
Utilized CORSIM to analyze alternative ramp patterns and lane
balance on 10 miles of urban controlled-access freeway widening and
reconstruction. Project added general purpose and frontage road capacity and
included as both reversible and concurrent-flow HOV lane sections.
US 83, Cameron County - TxDOT Pharr
District
Hidalgo County Line to Harlingen
Utilized CORSIM
to analyze proposed conditions on 8.7 miles of controlled-access freeway from
the Hidalgo County line to Harlingen to determine the optimal layout for
schematic development by others.
SH 71, Austin - TxDOT Austin District
IH 35
to US 183
Utilized CORSIM to analyze alternative ramp patterns and lane
arrangements for 5 miles of controlled-access freeway to determine the optimal
layout for PS&E development by others.
SH 6, Brazos County - TxDOT Bryan District
FM
2818 to Green's Prairie Road
Utilized CORSIM to analyze existing
operations and assist in the phasing of improvements to the interchange of SH 6
with Texas Avenue (Bus. 6). Proposed work includes ramp revisions and
intersection and frontage road improvements (including conversion to one-way
traffic) along 2 miles of SH 6.
FM 518 at FM 2094 and FM 270, Galveston County - TxDOT
Houston District
Utilized PASSER III, TRANSYT and NETSIM to analyze
existing conditions and to propose interim and long-range improvements to
improve traffic flow at closely spaced high volume intersections.
FM 2100 Railroad Grade Separation, Crosby - TxDOT Houston
District
Utilized PASSER III, TRANSYT and NETSIM to analyze
intersection and access road operations and assist in the alternative analysis
and preparation of design schematics for a railroad grade separation and 2
miles of a five-lane facility.
FM 1093, Fort Bend County - TxDOT Houston
District
FM 723 to FM 1464
Utilized PASSER III, TRANSYT
and NETSIM to optimize intersection geometry for the preparation of design
schematics for upgrading 8 miles of two-lane roadway to a four-lane divided
facility.
Spur 41, Sugarland - City of Sugarland
Utilized
CORSIM for the traffic analysis and alternative studies of interim and
long-range improvements to relieve congestion at the high volume US 90A
intersection and provide for a railroad grade separation.
Loop 363, Temple - TxDOT Bridge Division and Waco
District
Utilized CORSIM to analyze four distinct roadway options to
reduce a perceived weave conflict at the US 190/ Loop 363 junction as part of a
UPRR bridge replacement project.
US 69 / US 96 / US 287, Beaumont - TxDOT Beaumont
District
IH 10 to North of SH 105
Utilized the Highway
Capacity Software to analyze alternative ramp patterns and lane balance for the
alternative analysis and preparation of design schematics for 7 miles of urban
controlled-access freeway.
PR 22 (JFK Causeway) User Cost Study - TxDOT Corpus Christi
District
Waldron Road to Aquarius Drive
Performed a user
cost analysis to determine the contractor time overrun penalties required for a
construction project for 4.7 miles of urban freeway, rural divided highway and
urban roadway
IH 410 User Cost Study, San Antonio - TxDOT San Antonio
District
Ingram Road to Callaghan Road
